reading registry fails under windows 2008 R2 64 bits

[riovescu]

The example found in the config file fails. So I created a small vbscript:

Set objRegistry = CreateObject("Wscript.shell")
Key = objRegistry.RegRead("HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\WindowsUpdate\SusClientId")
WScript.Echo Key

It works fine from the command prompt but it fails in pandora_agent. I tried running pandora_agent as a service or command line application but the result is the same:

wsus.vbs(4, 1) WshShell.RegRead: Unable to open registry key "HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\WindowsUpdate\SusClientId" for reading.

any idea?
